EGG SHELLER Richard D. Kisner, Fairmont, W. Va. Application September 18, 1953, Serial No. 380,933

ll Claim. (Cl. 146-2) This invention relates generally to kitchen appliances, and pertains more particularly to an improved form of egg sheller.

A primary object of this invention is to provide an improved form of egg sheller which is so constructed as to rapidly and efliciently shell eggs.

Another object of this invention is to provide an improved form of egg sheller which is light in weight, small in size, and which is otherwise well adapted for the purposes for which it is intended.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a top plan View of the egg sheller;

Figure 2 is a longitudinal section taken substantially along the plane of section line 2-2 in Figure 1 showing details of internal construction; and

Figure 3 is a vertical section taken substantially along the plane of section line 33 showing further details of construction.

Referring more particularly to the drawings, reference numeral 110 designates the invention generally, which incorporates a pair of elongated members which are provided at their forward ends with the pivot block portions 12 and 14 including overlapping boss portion 16 through which a pivot pin 18 extends. The opposite ends of the members incorporate hand grips 20 and 22, while intermediate portions of the members are formed to present an egg receiving housing indicated generally by the reference character 24.

Considering first the upper member in Figures 2 and 3, it will be seen that the intermediate portion embodies a cup member 26 extending outwardly of the annular depression 28 which is bounded by the upright flange portion 30 which extends around the intermediate portion in the manner shown. The upper surface of the cup 26 is provided with an apertured nipple 32 upon which the neck 34 of a resilient bulb 36 is received, the purpose of this construction being presently apparent.

The intermediate portion of the lower member incorporates a frusto-conical section 38 which is open at its lower end, as shown, and which depends from the annular depressed portion 40 bounded by the depending flange 42, similar to the upper section. A resilient gasket including a frusto-conical main body portion 44 seating within the section 38 and also including a radial flange 46 is suitably secured as by glue or the like to the lower member, and it will be manifest that the flanged portion Patent 2,752,96d Patented July 3, 1956 46 thereof is squeezed between the abutment surfaces 48 and 50 of the upper and lower intermediate portion when the hand grips 20 and 22' are positioned as shown in Figure 2.

It will be noted that the hand grips 20 and 22 include the side flanges 52 and 54 which are formed as continuations of the annular flanges 30 and 42, respectively, and that the side flanges not only present a smooth hand grip surface but also reinforce the handle grip and generally strengthen the assembly. Likewise, the side wall portions of the cup 26 and the lower section 38 taken in conjunction with the annular flanges 30 and 42, respectively, and the depressions 28 and 40, respectively, also materially enhance the rigidity and sturdiness of the assembly.

In operation of the device, an egg indicated generally by the reference character 56, is initially prepared for shelling by gently cracking the shell at its: opposite ends and removing a portion thereof, as indicated in Figures 2 and 3. The larger end of the egg is then seated within the lower end of the section 38 with the gasket 44 forming an air-tight seal therewith, and the hand grips 2t? and 22 are engaged in one hand by the user and squeezed together so as to squeeze the gasket flange 4 6 and seal the housing 24. The user then squeezes the bulb 36 with his other hand which introduces air under pressure into the housing and will force the egg out of its shell through the open bottom of the section 38, as indicated by dotted lines in Figure 3.

It will be manifest that the upper or smaller end of the egg need be cracked and broken away only sufficiently to permit the air under pressure to act upon the upper end of the egg, while it is necessary for the larger end of the egg to be cracked sufficiently to allow the egg within the shell to be forced through the shell outwardly of the housing 24.

From the foregoing, the construction and operation of the device will be readily understood and further explanation is believed to be unnecessary. However, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the appended claim.

What is claimed as new is as follows:

An egg shelling device comprising a pair of elongated members pivotally secured together at one end and provided with hand grip portions at their other ends, said members having intermediate portions including opposed abutment surfaces disposed in closely spaced parallel relation when the hand grip portions are urged together, each of said members having a deformed section bounded by a corresponding abutment surface, one of said sections having an open bottom, a gasket member including a frusto-conical main body portion disposed within said one section and having a radial flange overlying its corresponding abutment surface, and means for introducing fluid under pressure into the chamber formed between said members.
